SPECIFICATION forming part of Letters Patent No. 532,375, dated January8, 1895.

'Application tiled March 3, 1894.

To a/ZZ whom t may concern:

Be it known that I, ALBERT L. HIGGINS, a 'citizen of the United States,residing at Bar Harbor, in the county-of Hancock and State of Maine,have invented a new and useful is a specification.

The invention relates to improvements in blacking boxholders.

The object, of the present invention is to provide a simple andexceedingly inexpensive blacking box holder, which will possess greatstrength and durability, and which will enable a box of blacking to besecurely clamped and held in convenient position for use, and which willpermit an empty box to be readily detached and a full box to be quicklyapplied.

The invention consists in the construction and novel combination andarrangement of parts hereinafter more fully described, illus-V trated inthe accompanying drawings and pointedv out in the claim hereto appended.

In the drawings:-Figure 1 is a perspective view of a blacking box holderconstructed in accordance with this invention, a blacking box beingapplied. Fig. 2 is a similar view, the blacking box being removed. Fig.3 is a longitudinal sectional view.A Fig. Il is a transverse sectionalview. Fig. 5 is a detail perspective view of the clamping jaws and theconnecting bolt. Fig. 6 is a detail view of one of the guides.

Like numerals of reference designate corresponding parts in all theigures of the draw- 1, designates a circular head or body provided witha handle 2, and having iiat upper and lower faces and vertical sideedges, and provided with a transversely disposed bore or opening 11, inwhich is located a connecting bolt 10, adapted to force clamping jaws 3,into engagement with the sides of a blacking box 7. The clamping jaws3,' are L-shaped, having straight lower portions 4, arranged fiatagainst the lower face ofthe body or head l; and the upward extendingportions 5, are arranged hat against the .ver-

sain No. 502,253. (No model.)

by this construction it will be seen that the body supports the L-shapedclamping jaws, and the latter are not liable to be readily broken orotherwise injured. v

v The L-shaped clamping jaws are further supported by guides 8,depending from the lower face of the circular head or body andpreferably consisting of rectangular staples, which are driven into thehead or body, the latter being preferably made of wood. The horizontalor lower portions 4, of the L-shaped clamping jaws are disposedtransversely of the head or body and the depending rectangular keepers8, are located adjacent to the side edges of the said head or body andare disposed longitudinally of the saine.

The bolt is provided at one end with a head. Its other end is threadedand has arranged on the latter a thumb nut 12; and the vertical portions5, of the L-shapedclamping jaws are provided with openings 9,registering with the transverse bore or opening of the head or body andreceiving the clamping bolt. By turning the thumb nut and screwing thesame inward on'the bolt, the L- shaped clamping jaws will be movedinward and caused to clamp the blacking box.

The vertical portions 5, of the clamping jaws, extend slightly above theupper'face of the head or body, and these projecting prtions 'haveinward extending spurs 6, disposed at an inclination and adapted toengage the oppositesides of a blacking box, and to tightly clampthesame. The arrangement of the spurs tends to vtorce the blacking boxtightly against the upper face of the head or body, and they aredisposed in pairs adjacent to the opposite side edges of the jaws.

It will be seen that the blacking box holder is simple and comparativelyinexpensive in construction, that it possesses great strength anddurability, and that the jaws may be readily separated to release anempty black--l ing box, or be moved together to clamp an'- other box,and that the L.-shaped clamping jaws conform to the exteriorconfiguration of the circular head or body.

Changes in the form, proportion and the minor details of constructionmaybe resorted l of rectangular form, depending from the lower face ofthe body and arranged adjacent to the opposite sides thereof, thetransversely disposed approximately L-shaped clamping jaws having theirdat lower portions arrangedon the lower face of the body and fitting inthe depending guides, the vertical portions of the jaws being arrangedagainst the opposite side edges of the body and projecting above theupper face of the same and provided with inward extending spurs, `andhaving openings arranged at the terminals of the opening of the body andregistering with the same, a transverse bolt passing through saidopenings and provided at one end with ahead for engaging the adjacentjaw and having its other end extended and threaded, and a nut arrangedon the extended end of the bolt and engaging the other jaw,substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

ALBERT L. HIGGINS.
